Yes, it could be argued it was the pitch, much like Netflix originally was. It's actually kind of wild how the streaming services are literally following the same path as cable television.

Here's a New York Times article from 1981 about it:

Although cable television was never conceived of as television without commercial interruption, there has been a widespread impression - among the public, at least -that cable would be supported largely by viewers' monthly subscription fees. These days, however, as cables are laid across the country and new programs constantly pop up to fill the gaping maw, cable experts are talking as glibly about the potential advertising revenues as they are about opportunities for programming.

''The floodgates for advertising on cable are down,'' says Michael Dann, a leading consultant on cable television. Indeed, even pay television, once assumed to be secure from commercial interests, is attracting some attention as a potential vehicle for advertising. Admittedly, such leading pay cable services as Home Box Office and Showtime, whose programming consists primarily of theatrically released films, staunchly maintain that they will never accept advertising.

Also, I'll just point out that people in here not knowing about this literally proves my point that if the changeover happened before you were born/early in your childhood, you'll just accept the change as "the norm" because you never knew anything different and had no reasons to question it. It's not about the intelligence of any generation of kids, it's just an inherent part of not knowing what happened before you were born, which is something every human experiences. It takes dedicated effort to find out that "the norm" isn't "the norm," for anyone. Also, on the flip, we're not particularly special for figuring out "the norm" isn't "the norm."
